The chance discovery of a vast ecosystem beneath the collapsed Larsen Ice Shelf will allow scientists to explore the uncharted life below Antarcticas floating ice shelves and further probe the origins of life in extreme environments. Researchers discovered the sunless habitat after a recent underwater video study examining a deep glacial trough in the northwestern Weddell Sea following the sudden Larsen B shelf collapse in 2002.
"This is definitely the biggest thing Ive ever been involved with in the Antarctic," said Eugene Domack, a professor at Hamilton College in New York and lead author of the report detailing the ecosystem. The article will be published in the 19 July issue of Eos, the weekly newspaper of the American Geophysical Union. "Seeing these organisms on the ocean bottom--its like lifting the carpet off the floor and finding a layer that you never knew was there."
Domack suggests the strong possibility that new species of marine life may be uncovered in continuing analyses of the area as ecosystem experts sample the site. The international expedition was there on a U.S. Antarctic Program cruise to study the sediment record in the area vacated by the former ice shelf. The crew recorded a video of the seafloor at the end of its mission and only later discovered a thriving clam community, mud volcanoes, and a thin layer of bacterial mats.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
